Nitrogen toxicity

I know this is nitrogen toxicity but i can't find anywhere saying the effects. I've flushed it and all, are these leaves going to recover? die?
any input is greatly appreciated =)

I saw dark green leaves and clawing along with twisted growth. I'm no expert by any means but it could have a little to much n and not enough p just my thoughts.. if it is too much n foliar spray calcium will help improve and get rid of bubbling or crinkling

how do you know it's nitrogen toxicity?
the symptoms your plant is displaying look a lot like that, or over watering... which it very well may be, since you flushed it.
 
i just figured it was nitrogen because of all the claw leaves, there are about 10 of them throughout the plant, and i did that to the leaves where they are twisted =), the temp stays at 76ish, not sure on the humidity.

That sharp 90degree angle on some of em is phosphorus imo and the general droopy claw is the n overdose. It looks like you have a ph issue to me cause the twisted growth and "banding" on the new growth probably from over fert. Take some pics of the lower leaves and the whole plant if you want more out of me. But again I'm not an expert so take it with a grain of salt

Imo its Not nitrogen toxicity. Looks like heat problems or just over feeding. What is your humidity at and what are you feeding them. Npk ratio? Take a look at this thread. It will give you a better understanding of the leaves crawling. [FONT=.HelveticaNeueUI]Hope it helps.

N tox manifests as CLAW. It shows very dark leaves, ripens later and trichomes dont develop as well on clawed plants. I just Kiev them out for hash because it takes all the chlorophyll longer to break down and affects taste. There's other things that contribute to claw but too much N will definitely do it.
